If I see two Nocturnes with Called Shot, can I play both of them before drawing a card, or do I have to draw 2 cards since Nocturne says 'if you look but don't draw'?

Ruling: You can play both Nocturnes before drawing any cards. Since you now have no relevant cards to look at, you damage cycle which does nothing.

Sequence:

• Look at top card and see first Nocturne
• Play first Nocturne without drawing
• Look at top card and see second Nocturne
• Play second Nocturne without drawing
• No cards remain to look at, so damage cycle does nothing
